I did not hit the reset button

I believe you for two reasons: The reset button would also reset the mpg, not just the miles driven, and it wouldn't magically change the contents of the fuel tank. For the fuel gauge to jump up 2 pips to full, somebody had to put gas in the car. No incline will do that, AFAIK. So I don't know if you have helpful gremlins out where you live or what, but it looks to me like somehow your car was filled, possibly at home, since it sounds like you live about a mile from the ice cream place (why not ride bikes that short distance and enjoy the weather?). Is it possible somebody emptied last year's gas can for the lawnmower or something into your tank and didn't tell you?

OTOH, I have tried to brush dust off the MFD, and accidentally triggered the reset button. But that's not what happened here.

 

OMG, a modern miracle.

 

Where did you buy your gas?
I want to get some of that!!ound:

 

Well, flaky things sometimes happen to the Prius. Maybe the 12V power to the MFD and combination meter (where the fuel gauge resides) was intermittent which forced a reset.

It will be interesting to see how many miles you can travel from this point, until the gauge drops back down two bars.

 

I don't think anyone here thinks or said that you are. I just think that some people made jokes because they do not know why your car says its full. I think that I was just some type of fluke. If you are still troubled by the occurrence, maybe you should take the vehicle into your dealership and explain the story.

 

My first Prius fill-up, the pump clicked off, and when I checked the gauge, it was showing 2 pips below full. I went inside and paid (less than $30...GREAT feeling) and when I came out and powered on the car, the pips were full...all pips were showing. Could something similar have happened?

 

Please do not take offense,I was not calling you stupid.
I still want some of that gas!!

 

Fill up the next time you are out. That should give the fuel system a chance to reset with a full tank.

Patrick, how many times were you told to read your owner's manual?
Everyone gets one of these gas adding moments courtesy of Toyota and you can find it in the manual, somewhere.

I'm just sorry I haven't had mine yet. :Cry:

I apologize if you think I was calling you stupid, I was not thinking that nor intended that. Somehow the car thinks there's more gas in the tank, and we don't think an incline was involved. Perhaps it went from a cool garage to sit in the sun and the gas expanded? This is just speculation.

I've noticed it takes a little while for the fuel gauge to rise all the way to where the tank actually is. Driving a half-mile will do it, so will running inside the store for a minute.

For the first time in nearly 3 years, last weekend I paid more than $30 for a fill-up ($32 and change @ $4.12/gal).

 

Maybe one of the kids hit the reset?

 

Early on I did have an "event" where I swear the MFD reset itself to 0. No change in fuel level, however. I just checked it off to a senior moment or gremlins or whatever. 2K miles later and no more problems.

I agree with whoever said to fill up and see what is really in the tank and let it reset itself.

166 miles and down to 2 PIPs doesn't sound right. Way too low unless you are driving with the emergency brake on. (just kidding). Really, I'm over 300 miles before I get down to 2 PIPs.

Gremlins. They haven't played with my "guess gauge" but they did push my window lock button. I know I was the "Idiot of the Day" at the dealer. The service writer said I was the 3rd one with "power window failure" cured by pressing the button. Just goes to show that stuff happens to everyone sooner or later regardless of tenure.

 

Gremlins are in the manual too, somewhere, I seen it.
